Version 5.9.7 - Unreleased

Note

In development. 5.9.7 isn’t released yet. These are the release notes for the upcoming release.

Note

If you are upgrading a cluster, you must be running CrateDB 4.0.2 or higher before you upgrade to 5.9.7.

We recommend that you upgrade to the latest 5.8 release before moving to 5.9.7.

A rolling upgrade from 5.8.x to 5.9.7 is supported.

Before upgrading, you should back up your data.

Warning

Tables that were created before CrateDB 4.x will not function with 5.x and must be recreated before moving to 5.x.x.

You can recreate tables using COPY TO and COPY FROM or by inserting the data into a new table.

See the Version 5.9.0 release notes for a full list of changes in the 5.9 series.

Fixes

  • Fixed an issue that could cause queries to run into a NullPointerException if having a query condition like (nonPrimaryKey = ? AND primaryKeyPart = ?)

  • Fixed an issue that caused FILTER clauses on non-aggregate window functions to be ignored instead of raising an unsupported error.

  • Fixed an issue leading to an error when exporting big tables via COPY TO to the Azure Blob Storage. This also has a positive effect on performance.

  • Fixed an issue that could prevent the creation of new partitions if data was written to a partitioned table during a rolling upgrade and that table had setting warmer.enabled specified before the upgrade.

  • Fixed an issue that incorrectly updated VERSION settings from information_schema.tables and information_schema.table_partitions for partitioned tables and their new partitions to the latest version following a node upgrade.
